Several distinct requests for the same patient / donor pair at a time are possible e.g. a blood typing and a CMV status, but each request has to be answered by an individual IDM_RES i.e. results must not be ”concatenated” to a single result message. Multiple IDM requests for the same patient / donor pair have to be disjoint (i.e. may not contain identical markers). The occurrence of multiple requests should be an exception. Usually, all markers required should be requested within one message.
